Yes, spicules are made of the same material as the rest of the sponge, primarily consisting of silica or calcium carbonate.

Yes, oil can float on a sponge, as sponges are typically made of porous materials that can absorb liquids. However, the oil will not be absorbed in the same way that water would be, due to oil's lower density and different chemical properties. Instead, the oil may rest on the surface of the sponge or fill its pores without being fully absorbed. The effectiveness of this process depends on the sponge's material and the type of oil.
